But it turns out that it's not too complicated to build your own, for the cost of about $3000. Two MIT grad students figured out how to do just that, and are distributing both manufactured systems and their designs through their website, Open Ephys. Their goal is to launch an open-source hardware movement in neuroscience, so researchers can spend less time worrying about the gear they need and more time doing experiments."

In fact I just checked their schematics.. no secondary isolation, and power taken from the USB or from an external PSU (not supplied or specified)

computer power supplies provide less isolation and allow higher leakage currents than a medical grade PSU, let alone one rated for BF. So it doesn't even meet basic electrical safety, let alone any other parts of IEC60601. I personally woun't want this used on me..
